Key legal question
Whether the bank-record request was an inadmissible fishing expedition or lacked potential relevance.
Extracted holding
The records were potentially useful for tracing financial flows and identifying other suspects; the request was not abusive or an impermissible fishing expedition.
Extracted reasoning
The Italian request concerned a broader corruption and money-laundering investigation. Even if the appellants' accounts were not directly linked at first sight, the documents could help reconstruct the money movements and the involvement of other persons. Swiss authorities apply only a prima facie review and leave the evidentiary assessment to the requesting state.
